Craft stick polyhedra

Updated Feb 2026. Added a 10 sided jig.

Update December 14, 2025. I've added a pdf which is a presentation I made at a maths conference on this, as well as 2 videos on how to put the sides together, https://youtu.be/-JqtQ-SBQBY for the square jig (it doesn't show rotation of the central sticks to triangulate the frame though) and https://www.youtube.com/watch?v=jKntpH0QPvk for just about any of the other jigs. Also put in pics of the coffee stirrers and straws used.

Original This is a set of tools designed to make sides, and then shapes out of craft sticks which are about 180 x 6 x 1.2mm, (otherwise known as coffee stirrers) small foldback clips, and 30mm sections of drinking straw. Shapes up to approx 70cm diameter are included. No glue is required unless you want to make things a bit more robust. From the plans here you can make all the platonic solids, and I will add an assembly video soon. There's a reference for the truncation sides sizes, see https://www.researchgate.net/publication/366578178_Circles_for_Maths_Art_Play_and_the_Circular_Economy . For some background, pics of what is to come and more variations, see my insta https://www.instagram.com/stevenurseau/ or a few blog posts starting from https://tribo3d.blogspot.com/2025/08/1d-to-3d.html Have Fun
